Zephyr is a subscription-based operating system tailored for developers working with embedded systems and IoT applications. It supports a variety of architectures, including x86, ARC, and ARM, and is designed to manage both application and kernel code in a single address space. Notable features include stack-overflow protection, thread isolation, and permission tracking for kernel objects and device drivers, making it suitable for a wide range of devices from simple sensors to complex controllers.

The platform is compatible with various user types, including startups, nonprofits, and enterprises. It integrates seamlessly with tools like EEZ Studio, Golioth, and Katalon Recorder, enhancing its functionality. Additionally, Zephyr provides an API and extensive documentation for user training, ensuring developers have the resources needed to implement tailored solutions effectively.
